对被囚禁原子质心运动基态波包的有效分束

Effective splitting of a trapped atomic wave packet in the motional ground state

文章简要地介绍了原子干涉现象及原子光学的发展历史和现状.在对各种不同的原子干涉仪工作原理进行简单总结之后,文章描述了包括文章作者在内的研究小组一项最新的理论工作.这个工作提出了一个对被囚禁原子质心运动基态波包进行有效分束的物理方案.

We briefly review the history and current progress in atom interferometry and atom optics. A descriptive summary of various types of interferometers is followed by a simple account of a new type of beamsplitter for trapped atoms, based on the theoretical idea recently published in Physical Review Letters by a group including ourselves. We show that a trapped atomic wave packet in the motional ground state can be coherently split into two paths effectively with two independent translating traps.
